What Increases Your Risk of Type 2 Diabetes and How Can You Prevent It?
Share
The occurrence of type 2 diabetes is closely related to genetic background and daily living habits. Type 2 diabetes can develop when the body gradually becomes resistant to insulin and the pancreas is unable to produce enough insulin to maintain normal blood sugar levels. Understanding these risk factors and their interactions can facilitate early preventive measures.
Genetic Factors and Family History
Unhealthy Eating Habits
Regular consumption of sugary drinks and lots of high-calorie foods can lead to weight gain, which increases the risk of developing type 2 diabetes. Long-term consumption of refined grains and insufficient intake of dietary fiber may also increase the risk of illness. However, type 2 diabetes is not caused by a single food, but is the result of the combined effect of multiple factors. Family dietary habits can influence a person's dietary choices from childhood, and genetic differences may also affect appetite, fat storage, and the response of pancreatic cells to changes in blood sugar. Replacing sugary drinks with plain water and appropriately increasing the intake of beans, vegetables, whole grains and fresh fruits can help manage blood sugar and weight.
Lack of Regular Exercise for a Long Time
Chronic physical inactivity may lead to insulin resistance and increase the risk of weight gain, which raises the likelihood of developing type 2 diabetes. Family members sometimes maintain a sedentary lifestyle together, such as sitting for long periods at work, watching TV or driving. These shared living habits may also interact with genetic susceptibility, further increasing the risk of illness. For most adults, it is a practical exercise goal to engage in at least 150 minutes of moderate-intensity physical activity per week and schedule two days of muscle-strengthening training. During the time of sitting, short walks can be interspersed to increase the total amount of activity throughout the day.
Overweight
Excessive body fat, especially the fat accumulated around the abdominal organs, increases the risk of insulin resistance, and the accumulation of fat in the liver and pancreas may also affect blood sugar regulation. Genetic factors can affect a person's appetite, energy expenditure and fat storage location, which also helps explain why obesity and type 2 diabetes often occur simultaneously in the same family. For overweight or obese adults with a high risk of illness, reducing initial weight by 5% to 7% is a common preventive goal.
Insulin Resistance
Insulin resistance and decreased insulin secretion are two different processes. Insulin resistance refers to the weakened response of muscles, liver and fat cells to insulin, making it difficult for the body to effectively utilize insulin to regulate blood sugar. Initially, the pancreas compensates by secreting more insulin, but as the disease progresses, the beta cells in the pancreas may gradually fail to produce enough insulin, leading to type 2 diabetes. Genetic factors also affect the function of β cells and the body's response to insulin, which to some extent explains why the risk of diabetes is often higher among close relatives.
How to Prevent Type 2 Diabetes?
Control Weight
For adults who are overweight or obese, losing 5 to 7 percent of their initial body weight can help reduce the risk of developing type 2 diabetes. Reducing excess body fat, especially belly fat, can help improve your body's sensitivity to insulin. In diabetes prevention programs, if high-risk groups aim to lose 7% of their weight and engage in at least 150 minutes of physical activity per week, their risk of developing diabetes can be reduced by approximately 58% within three years.
Daily diet should focus on the intake of carbohydrates, and pay attention to the nutritional composition of food. Long-term and excessive consumption of sweet foods, refined grains or sugary drinks can easily lead to excessive calorie intake and increase the difficulty of blood sugar management. In contrast, beans, whole grains and various vegetables can provide dietary fiber, which helps improve the overall quality of diet. When arranging each meal, it is advisable to prioritize the intake of vegetables, and then pair them with an appropriate amount of protein-rich foods such as fish and poultry, as well as staple foods like brown rice and potatoes. For fruits, it is recommended to choose whole fresh fruits rather than drinking fruit juice to retain more dietary fiber. Appropriately increasing the intake of protein and fiber-rich foods, while choosing unsaturated fat sources such as nuts and olive oil, can also help prolong the feeling of fullness and reduce unnecessary eating.
Regular Exercise
Reducing sedentary time and increasing daily activities are worthwhile lifestyle changes for the prevention of type 2 diabetes. For adults, consider a total of 150 minutes of moderate-intensity exercise per week as a reference. During exercise, heart rate and breathing may increase, but it usually does not affect normal conversation. In addition to cardio, you can build muscle strength with exercises such as dumbbells, elastic bands, or squats. Muscles are involved in glucose uptake and utilization, and maintaining a certain amount of muscle mass helps improve insulin sensitivity. For people who usually lack exercise, gradually changing is easier to stick to than suddenly increasing the amount of exercise. You can start by walking a short distance after each meal and reduce the situation of sitting still for a long time.
Ensure Adequate Sleep
Sleep quality and mental state are often overlooked health factors and are closely related to the body's ability to regulate blood sugar. Chronic sleep deprivation can interfere with insulin and affect appetite and energy metabolism, making weight management more difficult. In addition to ensuring sufficient rest time every night, one should also pay attention to whether sleep is continuous and whether it is easy to wake up. If severe snoring, interrupted breathing at night or listlessness during the day occur frequently, it is necessary to check in time whether there is a problem of sleep apnea. Continuous stress in work and life can indirectly increase the difficulty of glucose management by affecting hormone levels and daily behaviors. Allowing the body and mind to have proper rest and finding a suitable way to relieve stress for oneself can help maintain a more stable pace of life. Combined with other healthy habits, it can reduce the risk of type 2 diabetes.
Quit Smoking and Control Alcohol Consumption
Smoking and drinking alcohol are two notable examples of everyday habits that can add to your metabolic burden without your knowing it. The harmful substances in tobacco can affect the body's utilization of insulin. Long-term smoking is associated with an increased risk of type 2 diabetes. Quitting smoking can start by reducing the frequency of smoking, or one can adopt nicotine replacement therapy or other auxiliary measures under the guidance of a doctor to help reduce difficulties during the quitting process. When it comes to alcohol intake, one should avoid regarding drinking as a healthy habit. People without a drinking habit do not need to actively try it, while those with a drinking habit can gradually reduce the frequency of drinking and the amount consumed each time. At the same time, cocktails, sweet pre-mixed drinks and other beverages often contain extra sugar. When choosing them, one should also pay attention to their calorie and sugar content.
Regular Blood Sugar Testing
Type 2 diabetes may not have obvious symptoms in the early stage, so it is not possible to determine whether blood sugar is normal merely based on physical sensations. Regular screening helps to detect prediabetes in a timely manner and buys time for subsequent intervention. Common testing methods include A1C, fasting blood glucose, and oral glucose tolerance test. An A1C result of 5.7% to 6.4% usually indicates prediabetes. For those with normal initial screening results, it is generally recommended to have a check-up every three years. If one is already in the prediabetic stage, annual follow-up is usually required. Some people at higher risk may need more frequent monitoring. After being diagnosed with prediabetes, one can consult a doctor to see if it is suitable to participate in a systematic diabetes prevention program and to understand whether further intervention measures are necessary.
